Method for controlling output torque (Teng) of a propulsion unit in a vehicle powertrain comprising driven wheels drivingly connected to said propulsion unit via a mechanical transmission with a drive shaft, wherein said method comprising the steps of registering driver torque demand (Td) for vehicle propulsion, registering propulsion unit rotational speed (?e), and controlling said output torque (Teng) of said propulsion unit to asymptotically follow said driver torque demand (Td) using a closed-loop linear-quadratic regulator (LQR) based controller (9) having said driver torque demand (Td) and said propulsion unit rotational speed (?e) as input data, in order to minimize driveline oscillations. |
